Well the pans were made for Tony Branda, Cobra/ Shelby parts etc. I picked up one off of ebay "NOS" never used for $200! They sell new for $350 or so. The pick up will cost you maybe $45. The dipstick doesn't go into the
oil pan that I know of (at least not on mine). The small block
oil pans are more valuable in my opinion just because the Shelby's actually came with those and not aftermarket. Hope it helps. Matt
